You know how sometimes a mistruth becomes so popular that that it's impossible to refute it with facts or data? It becomes an urban myth. Like when people say City cheated FFP but won at CAS because of a technicality, or when people meme about Emptihad, etc. They aren't true, but it's just not possible to combat the wave of lies anymore.
This idea that Kevin is superfluous to our requirements, or that the first team is better off without him is one such urban myth. It's dangerous and I see more and more people parroting the same shit every match. Sooner or later the majority will start believing in the shared "truth" and turn on him.
Happened with Gundo from 2017 to 2019 and it took him a herculean effort and a complete reinvention of his role to change that narrative. Happens every match with Walker, where people still believe that the best defending RB in the world is "prone" to brain farts. God knows what lesser capable right backs are prone to then. Currently happening with Rodri where people just can't see what he does. He only passes sideways and is shite defensively according the shared "truth". Anyone feel a sense of Deja Vu? Remember a player called Gundogan being criticised for similar things? "A nothing player", "doesn't add anything to the squad", "a nice to have, but not a difference maker".
This may seem like paranoia, but give it time, and it will happen to Kevin too. I'm already seeing the pattern.
28 goals and assists in 36 starts in all competitions last season, almost a goal or assist every match but apparently we didn't need him. 7 goals and assists in 8 matches in the Champions League, but yeah he totally destabilizes the team.
